Bayesian approach to radio frequency interference mitigation
S. A. K. Leeney, W. J. Handley, E. de Lera Acedo
Interfering signals such as Radio Frequency Interference from ubiquitous satellite constellations are becoming an endemic problem in fields involving physical observations of the e…
Characterization Of Inpaint Residuals In Interferometric Measurements of the Epoch Of Reionization
Michael Pagano, Jing Liu, Adrian Liu +75
Radio Frequency Interference (RFI) is one of the systematic challenges preventing 21cm interferometric instruments from detecting the Epoch of Reionization. To mitigate the effects…
Use of Time Dependent Data in Bayesian Global 21cm Foreground and Signal Modelling
Dominic Anstey, Eloy de Lera Acedo, Will Handley
Global 21cm cosmology aims to investigate the cosmic dawn and epoch of reionisation by measuring the sky averaged HI absorption signal, which requires, accurate modelling of, or co…
Marginal Bayesian Statistics Using Masked Autoregressive Flows and Kernel Density Estimators with Examples in Cosmology
Harry Bevins, Will Handley, Pablo Lemos +3
Cosmological experiments often employ Bayesian workflows to derive constraints on cosmological and astrophysical parameters from their data. It has been shown that these constraint…
Marginal Post Processing of Bayesian Inference Products with Normalizing Flows and Kernel Density Estimators
Harry T. J. Bevins, William J. Handley, Pablo Lemos +4
Bayesian analysis has become an indispensable tool across many different cosmological fields including the study of gravitational waves, the Cosmic Microwave Background and the 21-…
Bayesian evidence-driven likelihood selection for sky-averaged 21-cm signal extraction
K. H. Scheutwinkel, W. Handley, E. de Lera Acedo
We demonstrate that the Bayesian evidence can be used to find a good approximation of the ground truth likelihood function of a dataset, a goal of the likelihood-free inference (LF…
